We look at the division of 79350806 by 630 
The aim is to understand the frequency of 630 in 79350806.

Advancing to step 1:
630 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 630

Let's proceed to step 2:
When dividing 79 by 630, we get 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 630

Step 3:
793 divided by 630 is 1 with a remainder of 163.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 630 from 793 and we're left with 163.
Include the next digit (5) from the dividend after 163, then repeat: 1635 / 630

Going ahead to step 4:
1635 divided by 630 is 2 with a remainder of 375.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1260 away from 1635, we end up with 375.
Include the next digit (0) from the dividend after 375, then repeat: 3750 / 630

Let's proceed to step 5:
630 goes into 3750 5 times with a remainder of 600.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Deduct 3150 from 3750 and we're left with 600.
Grab the next digit (8) from the dividend, add it to 600, then carry on: 6008 / 630

Step 6:
630 can be fit into 6008 9 times, resulting in a remainder of 338.
The number 9 becomes the next digit in our result. 
Result so far: 1259.0
If we take 5670 away from 6008, we end up with 338.
Grab the next digit (0) from the dividend, add it to 338, then carry on: 3380 / 630

Advancing to step 7:
If we divide 3380 by 630, we get 5 and a remainder of 230.
The next digit of our result is 5. 
Result so far: 12595.0
Subtracting 3150 from 3380 leaves us with 230.
Fetch the next digit (6) from the dividend, attach it to 230 and continue: 2306 / 630

Let's proceed to step 8:
630 goes into 2306 3 times with a remainder of 416.
Record the quotient 3 as the next digit in the result. 
Result so far: 125953.0
Subtract 1890 from 2306 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 9:
When dividing 4160 by 630, we get 6 with a remainder of 380.
The next digit of our result is 6. 
Result so far: 125953.6
Subtract 3780 from 4160 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 10:
630 goes into 3800 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 125953.66
If we take 3780 away from 3800, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 125953.66 with a remainder of 0.02.
